Feedback on PC Airflow Configuration

[Avess]

I have a Hyte y40 Case

360mm AIO top intake 

Rear 120mm Intake 

Bottom 140mm intake 

side 2x140mm exhaust 

would this config work or should I just put them normally?

Why don't you try it out and see if the temperatures are ok while gaming or whatever you use the computer for.  If temps are high then you might have to tweak a bit.  I see nothing wrong with this setup   If it works it works.  There is technically no right or wrong as long as you got some intake and some exhaust and manage to replace the air inside the case before it heats up.

Just curious, why intake through the AIO?

 

I would do AIO exhaust, rear exhaust, bottom and side intakes

Freshest air possible through the radiator, as it's the most important bit. I often do it with my AIOs and custom loop rads. GPUs don't usually mind the slightly warmer air they might get through a radiator, though assuming normal mounting and an axial cooler, the bottom intake will already be feeding fresh air into the GPU.

I disagree that it's the most important bit, because CPUs can handle pretty high temperatures but also an AIO does a good job cooling even with warmer air. There's still a big temp differential between the die and the air going through the radiator. But the heat from the CPU does affect the other components on the motherboard, the RAM, etc

 

Also why I'm a fan of blower GPUs

Odd as it seemed to me, counter-intuitively it cools better on intake in front than in any other position, especially with bottom fans, too. I assume this is because you're killing 2 birds with 1 stone by both pulling in fresh air AND cooling the CPU via the AIO,  as opposed to heating the AIO up with case air and the CPU, too.

I'm always running overclocked, so I want the CPU as cool as it can be. Modern chips (especially Intel's) are hot enough stock to hit thermal limits, so cooling those is also priority. Motherboard VRMs can run 24/7 at temps that would degrade a CPU, so long as you don't have a super weak VRM, they aren't really gonna care. The rest of the stuff on the mobo never gets that hot to begin with, we haven't had super spicy northbridges since X58 AFAIK. RAM doesn't really get that hot either. Most modern GPUs are massively overbuilt cooler-wise so warmer air hitting them is also a non-issue. Even older GPUs won't really struggle unless it's either a pathetic cooler, or some very spicy old card like OC focused GTX 780s or the higher SKU R9 200 series. 

 

TLDR: nothing else in the average PC is both as hot - while being as temp sensitive - as the CPU, so it's the priority for the freshest air, then GPU, then everything else. Most other bits either don't get that hot to begin with, or don't really give a damn about temps.

I just tried to flip my top to intake to feed fresh air to cpu. Cpu temps stayed the same while gpu increased by 6c. I’m back to the traditional back and top exhaust, front intake. This is with a tower cooler, not aio.

 

in general, the best config is a front mount rad set as intake with fans pushing air through it (or a push/pull for more flow) and the back and top set as exhaust.

I know some of you will hate me for this the whole point of my question was just because I waned my 140mm side intakes to look into the case because they look better that way they are the be quiet Light wings if anyone was wondering ...

Side intake blowing into the case is good because airflow is more likely to hit motherboard components. If set to suck out, you can still get dead spots close to the board

You should've told us in the first place so we can try to accommodate that, although some of us will still argue with you about it. Of course it'll work...
